Thinking of using these Posi trailer connectors. They are waterproof, snap together firmly and would make any servicing a snap. Designed for being in the harsh exterior world, they should survive under the seat just fine.

I gave up on using the Rowe Electronics fuse box. It's a nice unit, but.. always the but... it only distributes power leads. Somewhere, grounds have to connect. And the BlueSeas box does that. Elegeantly simple, relatively small, and it fits perfectly into the recessed area of the plastic pan.

And I learned that if you connect a postive wire directly to ground a fuse WILL blow. What I did not know is that when a modern fuse blows, it illuminates! Coolio!

Overview shot. The black connector at top is a PosiTap trailer connector. Left of it is the programmable delay relay for the aux tank fuel pump. I programmed it for 30 minutes run time before auto shutdown. Because I always forget. The ty-rap at middle right is for the seat release as I run a Russel DayLong.
